This study reports on crawling variability and differences in variability between infants with typical development (TD) and those with developmental delays. This longitudinal study included 0-year-old infants with no apparent dysfunction. The crawling movement in the video was coded objectively with reference to previous research. The infants were…

Gradients across socioeconomic status occur for many children's health and improvement in high-income countries. The objective is to explore infant growth and child development in four developed countries around the socioeconomic landscape. In this paper, Structural Equation Modeling (SEM) enhances the socioeconomic status gradients for the…

Musical training has long been viewed as a model for experience-dependent brain plasticity. Reports of musical training-induced brain plasticity are largely based on cross-sectional studies comparing musicians to non-musicians, which cannot address whether musical training itself is sufficient to induce these neurobiological changes or whether…

Previous research has highlighted the need to improve teacher education programs with the intent of preparing infant-toddler professionals as working with infants-toddlers and families requires a unique skill set. The following mixed methods research study supported these assertions by examining the early childhood education (ECE) undergraduate…

This paper reports the findings of a narrative review of international research literature about babies' and toddlers' engagement with the outdoor environment whilst attending ECEC (Early Childhood Education and Care) settings. Based on the in-depth review of 21 papers, it identifies four dominant themes in the literature: the outdoors as a space…

This study followed three preservice student teachers as they navigated a semester-long infant-toddler practicum designed to enact a relationship-based approach to teaching and learning. Selected participants were in particular and contrasting placement settings, which served as a catalyst for engaging in critical reflection in multiple ways.…

Background: Caring for persons with profound intellectual and multiple disabilities (PIMD) demands specific expertise. Tacit knowledge seems to play an important role, but little is known about its nature, including what is necessary for its development and transfer. Aim: To gain understanding of the nature and development of tacit knowledge…

How does parental causal input relate to children's later comprehension of causal verbs? Causal constructions in verbs differ across languages. Turkish has both lexical and morphological causatives. We asked whether (1) parental causal language input varied for different types of play (guided vs. free play), (2) early parental causal language…

Like many Montessori educators, the author was immediately drawn to the materials Maria Montessori designed for children in the conscious absorbent mind. They are simple, beautiful, and attractive to children. To many, including some parents, these materials are the essence of Montessori. However, Maria Montessori herself thought of her Method as…

Background: Between 90% and 95% of deaf children are born to hearing parents who often need support with how to adapt their communication. Parent-child interaction (PCI) is an important predictor of deaf children's future language development. It is therefore necessary for professionals to assess parents' strengths and needs to identify areas for…

Adults and children easily distinguish between fine-grained variations in trustworthiness intensity based on facial appearance, but the developmental origins of this fundamental social skill are still debated. Using a fast periodic visual stimulation (FPVS) oddball paradigm coupled with electroencephalographic (EEG) recording, we investigated…

Despite evidence that frequent progress monitoring to identify children at-risk of delays and inform early intervention services improves child outcomes, this practice is rare in infant-toddler settings where children could benefit the most from early intervention. Using a descriptive research design within an Implementation Science framework, we…

The aim of this study was to investigate the acoustic vowel space area in infant directed speech (IDS). The research question is whether the vowel space is expanded or remains constant in IDS. A corpus of spontaneous interactions of 9 dyads followed monthly from the age of 6 to 24 months was analyzed. The occurrences in the parents' speech of each…

Children's exposure to talk about conceptual categories plays a powerful role in shaping their conceptual development. However, it remains unclear when parents begin to talk about categories with young children and whether such talk relates to children's language skills. This study examines relations between parents' talk about conceptual…

Several researchers have found that media exposure through books or electronic media contribute to preschoolers' development. However, research with behavioral measures and during the first years of life have not been carried out in Latin American contexts. The aim of the following research was to evaluate the relations between media exposure…
